主要结果如下：1。以500个F 2单株为作图群体，利用150个共显性的SSR标记，构建了覆盖玉米全基因组的分子标记连锁图。

The major results are as follows. 1. A genetic linkage map containing 150 SSR markers was constructed based on an F2 population with 500 individuals.

计算机模拟表明， 此方法可以无偏地估计一个共显性标记与一个互作基因之间的重组率或连锁距离。

Computer simulations have shown that the methods proposed can unbiasedly estimate the recombination frequency or linkage distance between a codominant marker and an interactive gene.

得到清晰条带占所用标记总数的87.5%（35个标记），其中31对引物为共显性标记，4对引物为显性标记。

The results showed that 87.5% (35 markers) of the total number of markers obtained the clear bands, which 31 markers were co-dominant and 4 markers were dominant.
